Filed:

Dec 27, 2000

Appl. No.:

09/749983

International Classification:

A23G 330

US Classification:

426 5, 424 48, 424440, 426 3, 426 6

Abstract:

A method for producing a chewing gum with an improved release of a lipophilic active agent, as well as the chewing gum so produced, is obtained by using a hydrophilic gum base. The preferred and novel gum base includes hydrophilic polymers, hydrophilic softeners/emulsifiers and fillers, but is essentially free of hydrophobic elastomers and hydrophobic softeners, as well as waxes and elastomer solvents. The lipophilic active agent is preferably added to a coating on a chewing gum pellet made using a hydrophilic gum base, such as by being mixed into a coating solution. The coating solution may contain a high-intensity sweetener. An active agent may also be used in the gum core.

International Classification:

A23G 330

US Classification:

426 3, 424 48, 424440, 426 5

Abstract:

A method for producing a chewing gum with a controlled release of a bitterness inhibitor, as well as the chewing gum so produced, is obtained by physically modifying the release properties of the bitterness inhibitor by coating and drying. The bitterness inhibitor is coated by encapsulation, partially coated by agglomeration, entrapped by absorption, or treated by multiple steps of encapsulation, agglomeration, and absorption. The coated bitterness inhibitor is preferably then co-dried and particle sized to produce a release-modified bitterness inhibitor for use in chewing gum. When incorporated into the chewing gum, these particles are adapted to produce a fast release or a delayed release when the gum is chewed. The preferred bitterness inhibitor is sodium gluconate.

Assignee:

Wm. Wrigley, Jr. Co. - Chicago IL

International Classification:

A23G 330

US Classification:

426 3

Abstract:

The present invention is a method of increasing the flavor release of chewing gum using hydroxypropyl cellulose, as well as the chewing gum containing hydroxypropyl cellulose and having increased flavor release. The increase in flavor release is obtained by incorporating hydroxypropyl cellulose in a powder form directly into the chewing gum composition.

Abstract:

A method for producing a chewing gum with a controlled release of an antimicrobial agent, as well as the chewing gum so produced, is obtained by physically modifying the release properties of the antimicrobial agent by coating and drying. The antimicrobial agent is coated by encapsulation, partially coated by agglomeration, entrapped by absorption, or treated by multiple steps of encapsulation, agglomeration, and absorption. The coated antimicrobial agent is preferably then co-dried and particle sized to produce a release-modified antimicrobial agent for use in chewing gum. When incorporated into the chewing gum, these particles are adapted to produce a fast release or a delayed release when the gum is chewed. The preferred antimicrobial agent is chlorhexidine digluconate.

US Classification:

426 5, 424 48, 424440

Abstract:

A method for producing a chewing gum with an improved release of active agent, as well as the chewing gum so produced, is obtained by adding an active agent to a chewing gum coating. The active agent is added to the coating in a coating solution or premixed with a flavor or solvent. The coating solution may contain sweetener or other transdermal enhancing agents to obtain increased transmucosal absorption. An active agent may also be used in the gum core.
